摘要
介绍了火灾模拟软件SMARTFIRE的各个组成部分,就其实现模拟的具体步骤进行了阐述,并针对国内某地铁线路的典型双层岛式站台建立了模型,对某车厢着火的情况进行了数值模拟,获得了该火源状况下站台及着火车厢的烟气和温度场分布。希望能通过将来更深入的应用,为消防部队和有关部门提供火灾预测,为灭火救援的方案制定提供技术依据。
The main parts of SMARTFIRE software, one general purpose CFD fire simulation tool, and their functions are introduced first. The mesh generation, CFD engine and the visualization of the simulation results are illustrated. SMARTFIRE is used to numerically study the multiphase transport process of heat and smoke in a two-layer island type subway station under the fire scenario of a train car being in fire when it stays at the platform. Three-dimensional field simulation of the propagation of the temperature and smoke is carried out. The numerical results are used to provide the base for human evacuation and life-saving. With further and thorough application in future, it is anticipated that the related numerical simulation will provide prediction of fire and its evolution to the fire fighting troops and concerned departments, and provide the technique support for the establishment of tactics for fire fighting, human evacuation and life saving.
